Software Freedom Day 2008

"In a time when our lives are increasingly dependent on technologies, it is important we take the time to consider the impact of technology on our lives, and the importance of ensuring technology isn't used to limit us, but rather to take us further along a path of opportunity, innovation and freedom for all people."

"Software Freedom Day(SFD) is an event with hundreds of teams from all around the world running local events to help their communities understand Software Freedom."

www.softwarefreedomday.org

There was more than 500 events around the globe and more than 50 just in Brazil!

Me and my coworker Tom Mix Petreca planned 2 SFD events. One for my University and one for his.

 His event took place at Faculdade de Engenharia Industrial (FEI), in the beautiful afternoon of september 20th, 2008.


The presenters were Tom Petreca, Marcelo Arbore and Bruno Souza, known as JavaMan.

 

Bruno gave us a wonderful introduction in what is open source, why It affects us and how to bring money from It. Tom talked about software freedom and I discussed about OpenSolaris, an open source operational system.

My event was at Polytechnic School of University of São Paulo (Poili-USP), september 24th, 2008. The presentations started at 9 hours of a wednesday shining morning.


The presenters were Tom Petreca, João Samara and Marcelo Arbore.

Tom and João talked about open source and I gave presentation covering Open Solaris project. I also talked about Dtrace, Resource Manager and Zones, witch are technologies from Solaris operational system.

I Workshop on OpenSPARC Architecture at USP, Brazil.

A three-day workshop ocurred on march 2008 ( 24th, 25th and 26th) at São Paulo, having openSPARC specification and FPGA implementation as main subjects. The workshop happened from 24th through 26th March and was hosted by the Grupo de Sistemas Pervasivos e de Alto Desempenho (Pervasive systems and high performance group - PAD) of the Laboratory of Integrated Systems (LSI) of the Polytechnic School of the University of São Paulo (EPUSP). This was the first of many events related to the openSPARC center of excellence program at USP.

The introduction had the special participation of Carlos Thomaz and Eduardo Lima from Sun and Prof. Sergio Kofuji, coordinator of the PAD group. In the first day morning, the presentations introduced the principles and concepts of the openSPARC community and Sun’s Throughput Initiative. It showed the history, aspects and design decisions of the architecture. In the afternoon T1 and T2 particular issues were defined. The next day was very interesting, with nice presentations and a practical laboratory over the FPGA modeling theme. In the last day, we talked mainly about multicore specific aspects. You can see the full schedule PAD group webpage.

Prof. Sergio Kofuji gave me the opportunity to perform a presentation about the CMT and CoolThreads technology in the first day. The speakers were Sergio Kofuji, Jussara Kofuji, Fernando Muzzi, Edson Horta, German Santos, Stelvio Barbosan, Antonio Amorim, Eduardo Lima, Carlos Thomaz and Marcelo Arbore.

As you can see, this was a great meeting that gave outstanding information about the technologies that is leading the next generation of hardware multicores. Polytechnic School have a great role in history of brazilian computers hardware development, proudly having produced the first Brazilian computer inside its campus, called Patinho Feio, in 1972. SUN is a company that was born at the StanfordUniversity. There is no doubt that these two giants in hardware development working together can result nothing less than amazing projects.
